Abstract
A ground-fault circuit interrupter has a test circuit for generating a test fault current. The test circuit includes a test button, a first test resistor, and a regulating circuit constructed to generate a test fault current with a predetermined and substantially constant value independent of an applied voltage of an electrical network to be protected. The test button, the first test resistor and the regulating circuit are connected in series between phases of the electrical network.
Claims13
A network-voltage-independent ground-fault circuit interrupter having a test circuit for generating a test fault current, the test circuit comprising:
- a test button;
- at least one first test resistor;
- and
- a regulating circuit constructed to generate a test fault current with a predetermined and substantially constant value independent of an applied voltage of an electrical network to be protected, wherein the regulating circuit is electrically connected with phases of the electrical network only when the test button is closed.
